AKRON -- Developers who recently bought the University of Akron's old football stadium have dropped a plan to pursue a pro football team for the facility and are pitching a multi-use entertainment venue instead.

The proposal by Team 1 Marketing Group also includes adding a dome to the stadium known as the Rubber Bowl.

Team 1's Sean Mason tells the Akron Beacon Journal the goal is a spring 2015 opening for concerts and sporting events such as boxing, mixed martial arts and wrestling.

Brad Beckert, the city of Akron's development engineering manager, called that timetable ambitious if a dome is built.

Complicating the proposal is the possibility that Federal Aviation Administration approval might be needed for the dome because the Rubber Bowl is near the Akron airport.

Developers say they have new plans for the former football stadium known as the Rubber Bowl.
